Description

Display unit, eyeglass device and image system

Technical field

The present invention relates to a kind of display unit of show image, the viewing of assisted image eyeglass device and possess their image system.

Background technology

Popularized in recent years by the image system of three-dimensional perception for making image.Image system typically comprises the eyeglass device (such as with reference to patent documentation 1 and patent documentation 2) that display is watched by the display unit of the image of three-dimensional perception and assisted image.Display unit alternately shows the left two field picture formed for left eye observation and the right two field picture formed for right eye sees.Eyeglass device possesses the liquid crystal photic gate switching synchronously opening and closing with the display of left two field picture and right two field picture.Be configured in the liquid crystal photic gate before left eye to open during left two field picture is shown, close during right two field picture shows.Be configured in the liquid crystal photic gate before right eye to close during left two field picture is shown, open during right two field picture shows.Left two field picture and right two field picture represent the content of difference parallax.As the result of the synchronization action of above-mentioned liquid crystal photic gate, viewer perceives, thus can image shown by three-dimensional perception display unit to the parallax between left two field picture and right two field picture.

Synchronization Control between display unit and eyeglass device utilizes infrared ray or wireless signal to carry out.In fact eyeglass device is not connected with display unit, and thus spectators can watch image on desired position.

Suitable communication between display unit and eyeglass device is important for liquid crystal photic gate for the synchronization action of image display.But eyeglass device suitably cannot receive the signal sent from display unit sometimes.Such as, spectators from display unit remove sight line watch other directions time, eyeglass device easily receives the wrong signal from display unit.Or eyeglass device also can be subject to the impact of noise signal, produce misoperation.

In order to overcome the unreliability of the communication between display unit and eyeglass device, propose based on the control data extracted from the signal suitably received with the various eyeglass devices of inertia mode action.Even if this eyeglass device is not during suitably receiving the signal from display unit (not reception period), also based on the control data action obtained before not reception period, thus spectators can continue to watch the image shown by display unit aptly.

Liquid crystal photic gate action is made also to be useful for preventing the misoperation of the eyeglass device caused by noise signal based on the control data obtained in advance.Such as, if between the control data obtained in advance and the control data newly obtained, the opening and closing of liquid crystal photic gate has relatively big difference opportunity, then eyeglass device can judge that new control data is the data obtained by noise signal.

The change of the display action (display mode) of the image of display unit also requires the change of the synchronization action of liquid crystal photic gate sometimes.Such as, if the frame rate of image is changed, then need the operating frequency that the frame rate after making the synchronization action of liquid crystal photic gate and changing adapts.Or if spectators change the channel of display unit (such as television equipment), then the phase place of the periodic display action of display unit also can change sometimes.Now, liquid crystal photic gate needs to carry out on-off action with new phase place.

As mentioned above, eyeglass device utilizes the control data obtained in advance to make liquid crystal photic gate opening and closing in many cases.But the change of the frame rate of the image of display unit is difficult to switch instantaneously, the image synchronous signal of the display unit that (such as reaches the several seconds) during being transferred to the frame rate that should change is chaotic.Therefore, if directly export the control data of liquid crystal photic gate based on image synchronous signal, then also there is confusion in the on-off action of liquid crystal photic gate.Like this, the impact of the control data that the action due to liquid crystal photic gate is obtained in advance, therefore cannot switch to the image frame speed after change immediately.Such as, when switching from the display mode showing left two field picture and right two field picture respectively with 60Hz to the display mode showing left two field picture and right two field picture with 48Hz respectively, the on-off action of liquid crystal photic gate cannot also switch to the display mode of 48Hz instantaneously.During this period, the opening and closing of liquid crystal photic gate becomes irregular.

In addition, when the change of the image adjustment modes (the image quality pattern of such as television set) of display unit, sometimes not only carry out the adjustment of the image quality corresponding to image, but also change the opening and closing opportunity of liquid crystal photic gate.In the case, being also difficult to the control data of instantaneous change from display unit, also can there is confusion in liquid crystal photic gate side optical gate on-off action when shifting to this change.

In addition, even if sometimes provide a kind of when the control data from display unit is due to momentary interruption such as barriers, glasses side is also according to inertia operation (FlyWheel, inertia action) continuing action a period of time the opportunity of the control data detected before.But, in the inertia operation of these glasses, although wish switches display mode and changes the opportunity of liquid crystal photic gate, because liquid crystal photic gate carries out on-off action according to opportunity before sometimes, therefore asynchronous with image, the image seen by glasses is seemed glimmer (flicker).

If make the on-off action of liquid crystal photic gate occur chaotic or with the synchronous of image, confusion occur due to this reason, then spectators can feel the flicker caused by the nonsynchronous of eyeglass device or irregular on-off action.This can bring discomfort to spectators.

Above-mentioned flicker also can produce when display mode as described below switches.Such as, if display unit can not only show stereopsis (stereoscopic display mode), can also Alternation Display two different programs (the first program and second program) (dual display mode), then multiple spectators can optionally watch the first program and second program.The liquid crystal photic gate of the eyeglass device that viewing first segment object spectators wear is opened during the first program display, closes during second program display.The liquid crystal photic gate of the eyeglass device that other spectators wear is closed during the first program display, opens during second program display.The display mode of display unit, from stereoscopic display mode to the switching of dual display mode, for the liquid crystal photic gate of eyeglass device, requires the diverse action of synchronization action with stereoscopic display mode.But the impact of the control data that eyeglass device is obtained in advance, thus cannot perform the action adapted with dual display mode immediately.Like this, spectators can feel offending flicker.

The structure > of < image system

Fig. 1 is the skeleton diagram of the image system 100 of present embodiment.With Fig. 1, image system 100 is described.

Image system 100 possesses display is adjusted the adjustment action of the incident light quantity to left eye and right eye eyeglass device 400 by the display unit 200 of the image of three-dimensional perception and carrying out.As display unit 200, illustrate the various devices that television equipment or personal computer etc. can show stereopsis.

Display unit 200 comprises the display floater 210 for show image.On display floater 210, alternately show the left two field picture formed for left eye observation and the right two field picture formed for right eye sees.The content of left two field picture and right two field picture performance difference parallax.If only observe left two field picture with left eye, only use the right two field picture of right eye sees, then spectators are according to the parallax between left two field picture and right two field picture, can image shown by three-dimensional perception display floater 210.In the following description, the display mode of left for Alternation Display two field picture and right two field picture is called " stereoscopic display mode ".In the present embodiment, stereoscopic display mode illustrates as first mode.In addition, the sampling action of the display unit 200 of the left two field picture of Alternation Display and right two field picture illustrates as the first display action.In addition, display floater 210 illustrates as display part.

Shape and the vision correction glasses of eyeglass device 400 are similar.Eyeglass device 400 comprises optical gate portion 410, and this optical gate portion 410 carries out adjusting to the incident light quantity of left eye and right eye to make image by the adjustment action of three-dimensional perception.Left optical gate 411 before optical gate portion 410 has the left eye of the spectators being configured in wearing spectacles device 400 and the right optical gate 412 before being configured in right eye.

If close left optical gate 411, the light of the image shown by display floater 210 is hardly through left optical gate 411.Therefore, during left optical gate 411 is closed, the incident light quantity of left eye is reduced.

If open left optical gate 411, the light of the image shown by display floater 210 is by left optical gate 411.Therefore, during left optical gate 411 is opened, the incident light quantity of left eye is increased.

If close right optical gate 412, the light of the image shown by display floater 210 is hardly through right optical gate 412.Therefore, during right optical gate 412 is closed, the incident light quantity of right eye is reduced.

If open right optical gate 412, the light of the image shown by display floater 210 is by right optical gate 412.Therefore, during right optical gate 412 is opened, the incident light quantity of right eye is increased.

The light of the image that the term " incident light quantity " used in description of the present embodiment refers to shown by display floater 210 injects the amount of left eye and/or right eye.Optical gate portion 410 adjusts as described above by the opening and closing of left optical gate 411 and right optical gate 412 incident light quantity injecting left eye and right eye.In the present embodiment, optical gate portion 410 illustrates as light quantity adjustment part.Left optical gate 411 and right optical gate 412 use liquid crystal photic gate element.Replace, other optical elements that can be adjusted incident light quantity by the yawing moment adjusting image light also can be used as light quantity adjustment part.

When display floater 210 shows left two field picture, left optical gate 411 is opened, and right optical gate 412 is closed.When display floater 210 shows right two field picture, left optical gate 411 is closed, and right optical gate 412 is opened.Consequently, only observe left two field picture with left eye, only use the right two field picture of right eye sees.Spectators can according to the parallax between left two field picture and right two field picture, the image shown by three-dimensional perception display floater 210.

The on-off action in the optical gate portion 410 synchronous with the display of above-mentioned two field picture, according to agreement predetermined between display unit 200 and eyeglass device 400, realizes based on the control signal sent from display unit 200 to eyeglass device 400.In addition, the light quantity that control signal is not only carried out for above-mentioned optical gate portion 410 adjusts the control of action, also for making optical gate portion 410 perform other actions.Action based on the optical gate portion 410 of control signal will be explained hereinafter.

In the present embodiment, control signal is sent out as IR signal (infrared signal).Replace, control signal also can be RF signal (wireless signal).

Display unit 200 also comprises the transmitting element 220 for sending above-mentioned control signal to eyeglass device 400.Eyeglass device 400 also comprises the receiving element 420 for reception control signal.In the present embodiment, use sends ultrared light-emitting component as transmitting element 220.In addition, use the photo detector of receiving infrared-ray as receiving element 420.In the present embodiment, transmitting element 220 illustrates as sending part.In addition, receiving element 420 illustrates as acceptance division.

Fig. 2 represents the hardware configuration of display unit 200 and eyeglass device 400.The hardware configuration of display unit 200 and eyeglass device 400 is described with Fig. 1 and Fig. 2.

Display unit 200, except above-mentioned display floater 210 and transmitting element 220, also comprises decoding IC230, signal of video signal processing IC 240, sends control IC250, CPU260, memory 270 and clock 280.

Signal of video signal through coding is imported into decoding IC230.Decoding IC230 decodes to signal of video signal and with specified format image output data.As the coding of signal of video signal, illustrate the various modes such as MPEG (MotionPictureExpertsGroup, Motion Picture Experts Group)-2, MPEG4 or H264.

Signal of video signal processing IC 240 performs the signal transacting of the display about stereopsis, generates and exports the output signal of the input pattern signal being suitable for display floater 210.Signal of video signal processing IC 240 extracts the data corresponding to left two field picture and the data corresponding to right two field picture from the image data that decoding IC230 exports.Subsequently, display floater 210 is based on corresponding to the data of left two field picture and the data corresponding to right two field picture, the left two field picture of Alternation Display and right two field picture.

Signal of video signal processing IC 240 carries out other process to the image data that decoding IC230 exports.Such as, if signal of video signal processing IC 240 suitably adjusts the color of the image shown by display floater 210, then spectators can watch high-grade image.If the image of signal of video signal processing IC 240 to the interframe of the image data generated by decoding IC230 carries out interpolation, then improve the frame rate of image.

During display unit 200 is with stereoscopic display mode action, signal of video signal processing IC 240 carries out the signal transacting of the above-mentioned display about stereopsis.Signal of video signal processing IC 240, according to the signal of video signal being input to decoding IC230, performs the process for switching display mode.

Such as, if after the signal of video signal of the operating frequency of regulation " 60Hz ", the signal of video signal of the operating frequency of regulation " 48Hz " is transfused to decoding IC230, then signal of video signal processing IC 240 carries out the process for operating frequency being switched from " 60Hz " to " 48Hz ".In addition, term " operating frequency " refers to the display frequency of the group comprising left two field picture and right two field picture.Such as, " operating frequency of 60Hz " refers to and shows left two field picture with the frequency of 60Hz, and shows right two field picture with the frequency of 60Hz.

If after the signal of video signal of the action under regulation stereoscopic display mode, represent that the signal of video signal (the first image and the second image) of two different contents is imported into decoding IC230, then signal of video signal processing IC 240 carries out the process of the two field picture for the two field picture and the second image making display floater 210 Alternation Display first image.

If the first image is sports cast, the second image is cartoon program, then, during spectators (the first spectators) watch sports cast, another one spectators (the second spectators) can appreciate cartoon program.The eyeglass device 400 of the first viewers wear increases the incident light quantity to left eye and/or right eye during the first image display, and during the second image display, reduce the incident light quantity to left eye and right eye.The eyeglass device 400 of the second viewers wear increases the incident light quantity to left eye and/or right eye during the second image display, and during the first image display, reduce the incident light quantity to left eye and right eye.Therefore, multiple viewer can use single display unit 200 image that enjoy content is different simultaneously.In the following description, this display mode is called " dual display mode ".

The change of above-mentioned operating frequency (frame rate) or illustrate as the switching of display mode from stereoscopic display mode to the change of dual display mode.Display floater 210 illustrates using the action of the different operating frequency display frame image of the operating frequency of the display from two field picture or above-mentioned dual display mode as the second display mode.In addition, the second display mode also refers to the action of phase place display frame images different with the sampling action of the display unit 200 from the left two field picture of Alternation Display and right two field picture in stereoscopic display mode.Illustrate using the display action of different phase places and/or operating frequency display frame image as the second display action.Such as also can occur when spectators have switched the channel of display unit 200 from the first display mode to the switching of the second display mode.

Send the above-mentioned control signal that control IC250 generates the action in the optical gate portion 410 for controlling eyeglass device 400.In the present embodiment, control signal comprise the first display mode and the second display mode for the timing signals on opportunity during notifying to increase to the incident light quantity of left eye and right eye and the stop signal for making eyeglass device 400 stop the adjustment action of incident light quantity.

Send control IC250 and be created on display floater 210 with the timing signals sent during stereoscopic display mode show image.In addition, send control IC250 and be created on the stop signal sent when switching to other display modes (the second display mode) from stereoscopic display mode.Send control IC250 and control above-mentioned transmitting element 220, match with the display mode of the image shown by display floater 210, the transmission opportunity of adjustment timing signals or stop signal.In the present embodiment, send control IC220 to illustrate as signal generating unit.

Transmitting element 220 carries out the transmission of control signal under the control sending control IC250.

During display floater 210 is with stereoscopic display mode show image, transmitting element 220 sends timing signals to eyeglass device 400.The timing signals that the optical gate portion 410 of eyeglass device 400 receives based on receiving element 420, carries out above-mentioned on-off action.Consequently, during display floater 210 shows left two field picture, left optical gate 411 is opened, and right optical gate 412 is closed.In addition, during display floater 210 shows right two field picture, left optical gate 411 is closed, and right optical gate 412 is opened.

If switch from stereoscopic display mode to other display modes (the second display mode), then transmitting element 220 sends stop signal to eyeglass device 400.The stop signal that the optical gate portion 410 of eyeglass device 400 receives based on receiving element 420, stops the adjustment action of incident light quantity.In the present embodiment, if receiving element 420 receives stop signal, then left optical gate 411 and right optical gate 412 all maintain the state opened.Consequently, the state that the incident light quantity of left eye and right eye is increased simultaneously is kept.

CPU260 controls the various elements (IC230 that such as decodes, signal of video signal processing IC 240) of display unit 200.CPU260, according to the program be recorded in memory 270, input signal (such as from the signal of remote controller (not shown)) from outside, carries out the control of whole display unit 200.

Memory 270 as record CPU260 performed by program or program perform time produce ephemeral data region and be utilized.As memory 270, illustrate RAM (RandomAccessMemory, random access storage device) or non-volatile ROM (ReadOnlyMemory, read-only memory) of volatibility.

Clock 280 is provided as the clock signal of the action benchmark of CPU260 or other IC.

Display floater 210 is based on the output signal show image from signal of video signal processing IC 240.As display floater 210, illustrate the device of CRT mode, LCD (liquid crystal display), PDP (plasma scope) or use the device of organic electroluminescent.

Eyeglass device 400, except above-mentioned optical gate portion 410 and receiving element 420, also comprises CPU460, memory 470 and clock 480.

CPU460, according to the program be recorded in memory 470 or the control signal sent from the transmitting element 220 of display unit 200, controls eyeglass device 400.In the present embodiment, CPU460 illustrates as control part.

As mentioned above, during display floater 210 is with stereoscopic display mode show image, receiving element 420 receives timing signals.The timing signals that CPU460 receives based on receiving element 420, controls the adjustment action of the 410 pairs of incident light quantities in optical gate portion.Consequently, during display floater 210 shows left two field picture, left optical gate 411 is opened, and right optical gate 412 is closed.In addition, during display floater 210 shows right two field picture, left optical gate 411 is closed, and right optical gate 412 is opened.

As mentioned above, when the display mode of the image of display floater 210 switches to other display modes (the second display mode) from stereoscopic display mode, receiving element 420 receives the stop signal from transmitting element 220.The stop signal that CPU460 receives based on receiving element 420, allows the adjustment action in optical gate portion 410 stop.Consequently, left optical gate 411 and right optical gate 412 maintain the state opened.Like this, the state that the incident light quantity of left eye and right eye is increased simultaneously is kept.

Memory 470 is used as the place of the ephemeral data when record of the data of the program performed by CPU460 or maintenance program perform.

The timing signals that CPU460 receives from receiving element 420, generates the moment (opening the moment hereinafter referred to as a left side) about opening left optical gate 411, should close the moment (closing the moment hereinafter referred to as a left side) of left optical gate 411, should open the moment (opening the moment hereinafter referred to as the right side) of right optical gate 412 and should close the opportunity data in moment (closing the moment hereinafter referred to as the right side) of right optical gate 412.Memory 470 stores the opportunity data obtained by CPU460.In the present embodiment, CPU460 illustrates as data generating section.

CPU460 compares memory 470 opportunity data stored and the opportunity data newly obtained, and judges whether the timing signals corresponding to the opportunity data newly obtained is noise signal.Such as, if the opportunity data that the opportunity data newly obtained and memory 470 store has relatively big difference, then CPU460 can judge that the timing signals newly obtained is noise signal.

After the removing process of above-mentioned noise signal, the opportunity data that CPU460 utilizes memory 470 to store and the opportunity data newly to obtain carry out the calculation process of specifying, the opportunity during determining to increase to the increase of the incident light quantity of left eye and right eye.The left side that the opportunity data stored by memory 470 specifies is opened moment and the left side to be specified by the opportunity data newly obtained and is opened the moment and be averaged, to determine that the moment is opened on a left side by CPU460.The left side that the opportunity data stored by memory 470 specifies is closed moment and the left side to be specified by the opportunity data newly obtained and is closed the moment and be averaged, to determine that the moment is closed on a left side by CPU460.The right side that the opportunity data stored by memory 470 specifies is opened moment and the right side to be specified by the opportunity data newly obtained and is opened the moment and be averaged, to determine that the moment is opened on the right side by CPU460.The right side that the opportunity data stored by memory 470 specifies is closed moment and the right side to be specified by the opportunity data newly obtained and is closed the moment and be averaged, to determine that the moment is closed on the right side by CPU460.The result of this calculation process, can improve the reliability of the adjustment action in optical gate portion 410.In the present embodiment, CPU460 illustrates as determination section.

As mentioned above, receiving element 420 receives timing signals or stop signal, and CPU460 controls optical gate portion 410 based on timing signals or stop signal.If receiving element 420 receives stop signal after timing signals, and then again receive timing signals subsequently, then CPU460 can ignore the opportunity data from receiving the timing signals that receives before stop signal and obtaining, and controls optical gate portion 410 based on the opportunity data obtained from the timing signals again received.In the following description, the timing signals that receiving element 420 received before the reception of stop signal is called " at first timing signals ".In addition, the timing signals that receiving element 420 receives after the reception of stop signal is called " follow-up timing signals ".Further, illustrate as the timing signals of the first display mode at first timing signals.Follow-up timing signals as the second display mode timing signals and illustrate.

After the reception of stop signal, ignore based on the opportunity data at first timing signals, and control optical gate portion 410 based on the opportunity data obtained from follow-up timing signals, this is favourable to the reliability of the adjustment action in the optical gate portion 410 after display mode switching.Such as, if display floater 210 is with the operating frequency of 60Hz display stereopsis (the first display mode), subsequently with the operating frequency of 48Hz display stereopsis (the second display mode), then stop signal receive after left two field picture and display opportunity of right two field picture and stop signal receive before left two field picture and the display of right two field picture sometimes have relatively big difference opportunity.

If CPU460 does not ignore based on the opportunity data at first timing signals, and carries out above-mentioned handling averagely, then CPU460 can be subject to based on the opportunity data at first timing signals on the decision during increasing impact.Consequently, the adjustment action in optical gate portion 410 and the stereopsis under the operating frequency of 48Hz show asynchronous, and spectators can perceive flicker.

If CPU460 ignores based on the opportunity data at first timing signals, then CPU460 can not be subject to based on the opportunity data at first timing signals on the decision during increasing impact.Therefore, the adjustment action in optical gate portion 410 easily shows synchronous with the stereopsis under the operating frequency of 48Hz.

In the following description, receiving element 420 is neither received during timing signals does not also receive stop signal and be called " not reception period ".If memory 470 stores the opportunity data generated based on the timing signals received before not reception period, then the opportunity data that stores based on memory 470 of CPU460, the opportunity during determining to increase to the increase of the incident light quantity of left eye and right eye.Consequently, even if the communication occurred between display unit 200 and eyeglass device 400 is cut off, optical gate portion 410 also suitably can continue the adjustment action of incident light quantity.

The action > of < eyeglass device

Fig. 5 is the skeleton diagram of the pattern change of eyeglass device 400 during display unit 200 sends timing signals.The action of eyeglass device 400 during display unit 200 sends timing signals ground is described with Fig. 2 to Fig. 5.

The action of eyeglass device 400 changes between restriction mode, inertia mode and stop mode.

(restriction mode)

If acceptance division 425 suitably receives timing signals, then eyeglass device 400 is with restriction mode action.Under restriction mode, the action in optical gate portion 410 is retrained by timing signals.Open left optical gate 411 in the moment specified by left ON signal, close left optical gate 411 being closed the moment that signal specifies by a left side.In addition, open right optical gate 412 in the moment specified by right ON signal, close right optical gate 412 being closed the moment that signal specifies by the right side.

(inertia mode)

Due to barrier, noise or other factors of passing between spectators and display unit 200, the communication sometimes between display unit 200 and eyeglass device 400 can produce unfavorable condition.If the not reception period that acceptance division 425 does not suitably receive timing signals starts, then eyeglass device 400 is with inertia mode action.Under inertia mode, the action in optical gate portion 410 is based on the timing signals suitably received before starting at not reception period.

During acceptance division 425 suitably receives timing signals, store successively in storage part 475 such as about the information that the time of reception of signal is closed on signal, right ON signal and the right side is closed on left ON signal, a left side.If reception period does not start, then internal signal generating unit 463 generates internal signal based on the time of reception be stored in storage part 475.Consequently, even if suitably do not receive timing signals, optical gate portion 410 also can continue on-off action.

(stop mode)

For viewpoint and/or the reason that controls of the fail safe to spectators, the stop mode stopped under being set in the state that left optical gate 411 and right optical gate 412 open.Such as, if above-mentioned ground inertia mode continues for a long time, then synchronous can not get sometimes between the on-off action in optical gate portion 410 and the two field picture of display part 215 maintains.Or the viewing of long stereopsis brings burden to sometimes the eyes of spectators.Stop mode is set in order to avoid this unfavorable condition.On stopping under pattern, because optical gate portion 410 opens, therefore spectators can carry out desired action safely.

(transition between restriction mode and inertia mode)

During acceptance division 425 suitably receives timing signals, perform the action under restriction mode.After starting during neither receiving timing signals not receive again the reception (should be and do not receive) of stop signal, the action of eyeglass device 400 is changed from restriction mode to inertia mode.Internal signal generating unit 463 utilizes the length of the clock signal timing not reception period of self-clock 480.If exceed for before during the not predetermined threshold value of reception period in the time that internal signal generating unit 463 measures, acceptance division 425 suitably receives timing signals, then eyeglass device 400 is with restriction mode action again.

(transition between inertia mode and stop mode)

If the time that internal signal generating unit 463 measures exceedes for during the not predetermined threshold value of reception period such as several minutes, then internal signal generating unit 463 exports the internal signal being used for making the on-off action of light quantity adjustment part 415 (optical gate portion 410) to stop to fader control portion 464.Consequently, the action of eyeglass device 400 changes from inertia mode to stop mode.Eyeglass device is in the state do not received for a long time, thus by stopping the action of eyeglass device to realize economize on electricity.

(transition between stop mode and restriction mode)

If acceptance division 425 receives timing signals during stop mode, then open the moment with the left side determined based on this timing signals, the moment is closed on a left side, the moment is opened on the right side and the right side is closed moment relevant information and is stored to storage part 475 successively.If in order to enough information is stored to storage part 475 during determined to increase the increase to the incident light quantity of left eye and right eye by internal signal generating unit 463, then the action of eyeglass device 400 is restriction mode from stop mode transfer.

With Fig. 2 to Fig. 5 illustrate display unit 200 send stop signal during the change of pattern of eyeglass device 400.In addition, during term " not reception period " refers to be not only timing signals, stop signal is not appropriately received yet.In addition, the inertia mode during display unit 200 sends stop signal is identical with the inertia mode illustrated with reference to Fig. 5.

If receive stop signal with the acceptance division 425 of the eyeglass device 400 of restriction mode action, the action of eyeglass device 400 is shifted from restriction mode to stop mode.As mentioned above, the reception of stop signal means the change of the display mode of display part 215.As the result of the change of display mode, the display change on opportunity of two field picture.In the present embodiment, due to the reception along with stop signal, the action in optical gate portion 410 stops, and thus viewer perceives is less than by the asynchronous caused flicker between the on-off action in optical gate portion 410 and the display of two field picture.

In the present embodiment, the sending part 225 of display unit 200 sends stop signal repeatedly with predetermined number of times.Then, sending part 225 matches with the image shown with new display mode (the second display mode), sends timing signals to eyeglass device 400.

The timing signals (follow-up timing signals) sent under the acceptance division 425 of eyeglass device 400 is received in new display mode.Analysis portion 462, based on follow-up timing signals, obtains that the moment is opened on a relevant left side, the moment is closed on a left side, the moment is opened on the right side and the information in moment is closed on the right side, and is recorded in storage part 475.Internal signal generating unit 463 is ignored be recorded in control information in storage part 475 before stop signal is received, and open the moment based on the relevant left side obtained from follow-up timing signals, the moment is closed on a left side, the moment is opened on the right side and the information in moment is closed on the right side, generates internal signal.Internal signal generating unit 463 opens the moment to the left side obtained from multiple timing signals, the moment is closed on a left side, the moment is opened on the right side and the right side is closed the moment and performed such as handling averagely respectively, based on by after average the moment is opened on a left side, the moment is closed on a left side, the moment is opened on the right side and the right side is closed the moment and generated internal signal.Stop mode last till for internal signal generating unit 463 generate the enough follow-up timing signals of internal signal received till.Internal signal generating unit 463 generates internal signal, and after making light quantity adjustment part 415 (optical gate portion 410) action, restriction mode is transferred in the action of eyeglass device 400.

As mentioned above, under restriction mode, the operating frequency of eyeglass device 400 is finite value.Eyeglass device 400 receives the instruction group of stereoscopic display mode described later or dual display mode continuously.Consequently, eyeglass device 400 is subject to the constraint of the frame rate specified by instruction group, makes optical gate portion 410 opening and closing.Therefore, spectators can the suitably image that shows under stereopsis or dual display mode of perception.When suitably not receiving instruction group described later or when operating frequency there occurs variation, eyeglass device 400 enters inertia mode.Consequently, eyeglass device 400 can continue the on-off action in optical gate portion 410.But if eyeglass device 400 have received stop signal, then eyeglass device 400 enters stop mode forcibly.Further, during stop mode, optical gate portion 410 maintains open mode.

In stopped mode, the operating frequency of eyeglass device 400 is infinitary value, and optical gate portion 410 stops.In order to ensure the safety of spectators, if on-off action stops, then optical gate portion 410 maintains open mode.Consequently, spectators can not hinder by optical gate portion 410 and look about surrounding space.Further, as long as eyeglass device 400 continuous reception stop signal, then optical gate portion 410 maintains open mode.If the eyeglass device 400 being in stop mode receives the instruction group of stereoscopic display mode described later or dual display mode, then eyeglass device 400 transfers to restriction mode from the time of reception of this instruction group after designated duration.Consequently, eyeglass device 400 makes optical gate portion 410 action with the operating frequency of specifying (finite value).In addition, eyeglass device 400 receives stop signal, and optical gate portion 410 is in open mode for the time being, when temporarily not receiving the signal of stereoscopic display mode or dual display mode, even if do not receive stop signal, the optical gate portion 410 of eyeglass device 400 also can be made to remain open mode.

As mentioned above, inertia mode starts when suitably not receiving instruction group.The eyeglass device 400 being in inertia mode continues the opening and closing in optical gate portion 410 according to the instruction group formerly received.The operating frequency of inertia mode at least maintains the several seconds.If the eyeglass device of inertia mode 400 receives instruction group again, and the operating frequency specified by the instruction group again received is maintained, then eyeglass device 400 is with restriction mode action.Or if the eyeglass device of inertia mode 400 receives instruction group again, and the operating frequency specified by the instruction group again received is reset, then eyeglass device 400 is with restriction mode action.If do not receive instruction group at designated duration from inertia mode starts, then eyeglass device 400 is transferred to stop mode from inertia mode.

The action > that < switches from stereoscopic display mode to dual display mode

The action of display unit 200 and eyeglass device 400 when switching from stereoscopic display mode to dual display mode is described.Further, about the action when explanation of action during following switching is suitable for from stereoscopic display mode to other display modes (the second display mode) too and switches to stereoscopic display mode from other display modes (the second display mode).Such as, when image switches from the content of film to the content beyond film by spectators, or when spectators change the channel of the program shown by display unit 200, the frequency of the two field picture display of display unit 200, phase place change.In the present embodiment, as the result of the communication of the stop signal changed with display mode, the flicker between the conversion period that can prevent display mode.

Figure 14 is the sequential chart representing the stop signal sent when there occurs and switching to the display mode of dual display mode from stereoscopic display mode.With Fig. 1, Fig. 3, Fig. 4, Fig. 8, Fig. 9 and Figure 14, stop signal is described.

The part (a) of Figure 14 illustrates that display mode switches the opportunity of front two field picture shown by display part 215.The part (c) of Figure 14 illustrates that display mode switches rear two field picture shown by display part 215.As the part (a) of Figure 14 and partly shown in (c), along with the switching of display mode, the display change on opportunity of two field picture.

The part (b) of Figure 14 illustrates the stop signal that the switching along with display mode is received and dispatched.After display mode is switched, the sending part 225 of display unit 200 sends to be had the command signal CS of the pulse pattern represented with 16 system numbers " 2Dh " and has the command signal CS of the pulse pattern represented with 16 system numbers " 39h ".When the pulse pattern of the signal that the acceptance division 425 of eyeglass device 400 receives is the combination of " 2Dh " and " 39h ", analysis portion 462 judges to have sent stop signal.The command signal CS of pulse pattern " 39h " does not use under stereoscopic display mode and dual display mode.On the other hand, the command signal CS of pulse pattern " 2Dh " is all used when stereoscopic display mode and dual display mode.

If the command signal after the command signal of pulse pattern with " 2Dh " with the pulse pattern of " 39h " is received, then the analysis portion 462 of eyeglass device 400 explains that left optical gate 411 and right optical gate 412 should maintain the state opened.

Herein, the command signal CS sent under stereoscopic display mode and dual display mode and all comprise the command signal CS of the pulse pattern with " 2Dh " as the group of command signal CS that stop signal sends.In addition, the command signal CS with the pulse pattern of " 2Dh " is defined as the initial command signal sent in whole command signal combination.Therefore, the analysis portion 462 of eyeglass device 400 can be that benchmark carries out various judgement to have the command signal CS of the pulse pattern of " 2Dh ".Such as, the analysis portion 462 of eyeglass device 400 according to the command signal CS sent after having the command signal CS of the pulse pattern of " 2Dh ", can determine the action that eyeglass device 400 should perform.In addition, the analysis portion 462 of eyeglass device 400 based on the receiving cycle of command signal CS of pulse pattern with " 2Dh ", can determine the display cycle (i.e. operating frequency) of the two field picture of display part 215.The signal that the signal sent under various display mode and display mode send when switching comprises the command signal CS of common pulse pattern, its result, the acts of determination (explanation to received signal) of the analysis portion 462 of eyeglass device 400 is not vulnerable to the impact of noise.In the present embodiment, the command signal CS with the pulse pattern of " 2Dh " illustrates as common instruction signal.In addition, the command signal with the pulse pattern of " 39h " adjusts the notification instruction signal of the stopping of action as notice incident light quantity and illustrates.

In the present embodiment, the sending part 225 of display unit 200 such as sends more than 5 times stop signals.If acceptance division 425 such as receives 5 stop signals, the analysis portion 462 of eyeglass device 400 explains that left optical gate 411 and right optical gate 412 should maintain the state opened.Consequently, the action of eyeglass device 400 is not vulnerable to the impact of noise signal.

The sending part 225 of display unit 200 sends the command signal CS (with reference to Fig. 8 and Fig. 9) corresponding with dual display mode subsequently.If acceptance division 425 such as receives 5 stop signals, the analysis portion 462 of eyeglass device 400 explains the on-off action that should perform the optical gate portion 410 corresponding with the second display mode.

Figure 15 is the sequential chart of the transmission pattern variation roughly represented with the display mode switching command signal CS from stereoscopic display mode to dual display mode.With Fig. 8, Figure 14 and Figure 15, the variation of the transmission pattern of declarative instruction signal CS.

Illustrated by with reference to Fig. 8, the command signal CS during stereoscopic display mode, with the pulse pattern of " 2Dh ", as left ON signal LO, sends successively with the designated period " T " corresponding with operating frequency.The command signal CS with the pulse pattern of " 33h " closes signal LC as a left side, sends successively with the designated period " T " corresponding with operating frequency.The command signal CS with the pulse pattern of " 35h ", as right ON signal RO, sends successively with the designated period " T " corresponding with operating frequency.The command signal CS with the pulse pattern of " 2Bh " closes signal RC as the right side, sends successively with the designated period " T " corresponding with operating frequency.

Illustrated by with reference to Figure 14, if switch from stereoscopic display mode to dual display mode, then send stop signal.The command signal CS with the stop signal of the pulse pattern of " 2Dh " sends from the command signal of the pulse pattern of " 2Dh " as left ON signal LO transmission before after the cycle " T ".The command signal CS with the stop signal of the pulse pattern of " 39h " sends from the command signal of the pulse pattern of " 35h " as right ON signal RO transmission before after the cycle " T ".

The periodicity of the command signal of the timing signals that the transmission control part 255 of display unit 200 sends during making the periodicity of the command signal of stop signal send pattern and stereoscopic display mode sends and adapts.As mentioned above, the command signal CS with the stop signal of the pulse pattern of " 2Dh " utilizes as timing signals and stop signal, and, between timing signals and stop signal, have the transmission constant on opportunity of the command signal of the pulse pattern of " 2Dh ", thus eyeglass device 400 suitably can judge whether the signal with the pulse pattern of " 2Dh " that acceptance division 425 receives is noise signal.The transmission opportunity with the command signal CS of the pulse pattern of " 39h " sent after the command signal of pulse pattern with " 2Dh " also with stereoscopic display mode during send the command signal CS of timing signals one of them (in the present embodiment, for having the command signal CS of the pulse pattern of " 35h ") transmission consistent for opportunity, thus the analysis portion 462 of eyeglass device 400 reception opportunity of command signal CS of receiving during can comparing reception opportunity of the command signal CS of the pulse pattern with " 39h " and stereoscopic display mode, carry out noise judgement equally.

The control data relevant with the stop signal suitably received is stored in storage part 475 by analysis portion 462 under above-mentioned noise judges.Internal signal generating unit 463, based on the control data relevant with stop signal in storage part 475, stops the action of light quantity adjustment part 415 (optical gate portion 410).Consequently, left optical gate 411 and right optical gate 412 maintain the state opened and stop.

Then, the sending part 225 of display unit 200 coordinates the display of the two field picture under dual display mode to send timing signals.The control data relevant with the timing signals sent under dual display mode is stored in storage part 475 by analysis portion 462.Internal signal generating unit 463 is recorded in the control data in storage part 475 before not utilizing and receiving stop signal, and generates internal signal based on the timing signals (timing signals corresponding with dual display mode) of new record.Consequently, the on-off action again in optical gate portion 410 and the display of the two field picture under dual display mode suitably synchronous.

As mentioned above, in order to prevent stopping upper action outside the intention of eyeglass device 400, eyeglass device 400 performs when have received stop signal continuously at least 5 times and stops action.If receive stop signal continuously, eyeglass device 400 within the fixed period, transfers to stop mode from the pattern performed before this from the reference moment (time of reception of the initial pulse P1 of the command signal of 2Dh) of " 2Dh " of the halt instruction group received at first.If other command signals are received, then eyeglass device 400 from the reference moment of other command signals within the fixed period, transfer to the pattern specified by other command signals.

The instruction group of stop mode during display two two field pictures (left two field picture and right two field picture) in be sent out.The transmission synchronized transmission on opportunity of the command signal sent in the transmission opportunity of stop signal and former action.

In the transmission pattern illustrated with reference to Figure 15, the command signal of " 2Dh " of stop signal sends from the command signal of " 2Dh " formerly after two image durations.Equally, the command signal of " 39h " of stop signal sends from the command signal of " 35h " formerly after two image durations.Time of reception of the command signal of " 2Dh ", " 39h ", " 35h " based on the initial pulse signal P1 of these command signals the time of reception and determined.

Because all instruction groups all comprise the command signal of " 2Dh ", if so eyeglass device 400 receives the command signal of " 2Dh ", then eyeglass device 400 can predict the command signal again receiving " 2Dh " after two image durations.Equally, eyeglass device 400 can based on the time of reception of the command signal of " 35h " formerly, the prediction command signal of " 39h " or the time of reception of other command signals.Therefore, eyeglass device 400 is not vulnerable to the impact of noise.
